I have been loyal to your company for a long time now. My jellyfish is named Beth. She has been on my phone for 5 days now. I enjoy playing with her and I love wacthing her eat. Only one thing, make it a little harder for the jellyfish to get hungry (also make it harder for the jellyfish to die)
Edit: recently, I logged on and saw this pop up, it said, “your Beth has died, let’s grow the new one.” I was offline for like one day. Whenever I log on, I need to take care of rainbow and I cry.... still a good game tho 🙂👍
Edit: Rest In Peace; rainbow

Beautiful and well-made app!

Jellyfish gives me a moment of zen during my busy and stressful day. A large part of that moment is the music - it’s perfect. The notifications are 100% needed for me to keep the jellyfish alive and also to get that moment of zen. I would forget about it otherwise. Really well done ✅

Mellow Jelly

I’ve had my Jelly Belly through two tank upgrades, and I hope there’s another one soon, as it’s a pretty tight fit. 🤣 This is a calming wind-down, with lovely music, soft lighting (that can be changed to suit a mood), and a deep ocean vibe. Simple, no bells, no whistles, just…nice.
